Spanx invented this category and iterated it for two decades; Honeylove showed up selling the one thing compression knit can't do — hold a line with actual boning. That's the whole fight in one sentence: heritage firm-knit against corset-adjacent engineering, with $25 between them at full price and less than that whenever OnCore goes on sale. The sizing stories point in opposite directions too, which is where cross-shoppers get burned.
Opposite sizing stories
Honeylove says order your measured size, and reviewers largely back it up. OnCore's reviews repeat one line more than any other: it runs about a size small. So the same shopper often lands one letter apart in these two stores — measured size at Honeylove, sized up at Spanx. And Honeylove's chart is narrower per size: its XL covers a 34–36 inch waist while Spanx's XL runs 36–39, so the letters genuinely don't translate. Inches do — the translator below runs your two measurements against all three big brands' charts.

Honeylove SuperPower Short
The only one of the big three built with actual boning — structure, not just compression. That's why it's the event pick: boning holds a line the way knit fabric can't. The trade, and reviewers are unanimous on this: you will feel it, and getting it on takes commitment.
- The only one with boning — real structure
- Strongest compression class of the three
- Designed specifically as an event-grade piece
- Priciest per garment
- Reviewers consistently call it a wrestle to put on
- You will not forget you are wearing it
Fit note: runs true to size per Honeylove's own guidance — order your measured size for the full structural effect. The brand says sizing up is fine if you'd rather have lighter compression; just know that's the trade you're making.

Spanx OnCore Mid-Thigh Short
The middle path: firmer compression than Skims without Honeylove's boning or its price, from the brand that invented the category. It also goes on sale often enough that paying full price is optional if you can wait a week or two.
- Firm compression at a mid price
- The category original — two decades of iteration
- Goes on sale often
- Buyer reviews consistently say it runs about a size small
- Reviewers report waistband roll during long wear
Fit note: if you're between sizes, size up — 'runs small' is the most common line in its reviews. If today's price looks high, check back before paying full freight.

When the $25 is worth it — and when it isn't
Picture the occasion. If it's the kind where photographs outlive the evening — a wedding, a reunion, the milestone birthday — the boned piece earns its premium, because a held silhouette is visible in pictures in a way firm smoothing isn't. If the occasion is "fitted dress, long dinner, no photographer," OnCore's firm compression does the visible work for less, and on a sale week the decision nearly makes itself. The mistake is paying the Honeylove premium for OnCore occasions, or expecting OnCore to do boning's job.
One warning for bodies in transit
Both of these are precision garments — they do their jobs only at the right size, and neither is worth tailoring. If your size is still moving, buy for the date on the calendar in the size you measure that week. An $89 structural piece bought a season early is the most expensive way to own something that fits nobody.
The Verdict — Cut Along the Dotted Line
The night matters more than the money: Honeylove, measured size, the week of the event. The money matters more than the night: Spanx OnCore, sized up, on a sale week. Either way: this size, not your next one.
Asked at the counter
Is Honeylove or Spanx better?
Both are firm-control picks; the difference is construction and price. Honeylove SuperPower ($89) is built with boning — actual structure, the strongest hold in the aisle, and the piece to wear when the night is photographed. Spanx OnCore ($64) is firm compression without boning, $25 less at full price and frequently on sale. If the event is singular, Honeylove; if the budget is the tiebreaker, OnCore on a sale week.
Does Spanx OnCore run small?
The most common complaint in OnCore buyer reviews is that it runs about a size small — if you’re between sizes, size up. Honeylove is the opposite story: the brand says it runs true to size and to order your measured size for the full structural effect.
Is Honeylove worth $25 more than Spanx?
Only if you need what the $25 buys: boning. It holds a silhouette the way compression knit cannot, and it’s why Honeylove is the event pick. If your occasions need firm smoothing rather than a held line, OnCore does that for less — especially on one of its frequent sales, when the gap widens past $25.
Which is easier to actually wear?
Neither is the comfort pick — that’s Skims territory. Between the two: OnCore reviewers report waistband roll during long wear; Honeylove reviewers report a wrestle getting it on and constant awareness of the boning. Plan either for hours, not days.
